Document Summary

Divisions of the nervous system: cns- central nervous system: responsible for analyzing and interpreting information , pns- peripheral nervous system: responsible for collecting and sending stimulus. Views of the brain: dorsal, ventral, lateral, medial (midline) ! Terminology : anterior: rostral (ahead or front), posterior: caudal (behind or towards the back), dorsal: back, ventral: front or belly, midline: the central axis, medial: towards the middle/midline, contralateral: opposite side ! Planes through the brain: midsagittal: divides body into medial and lateral segments (side-side), horizontal: divides body into superior and inferior segments (top-bottom), coronal: divides body into anterior and posterior segments (front-back)! Two cerebral hemispheres divided ! by the sagittal ssure (midline)! Concerned with contralateral ! sensation and movement ! Major parts of the cns: cerebrum-cerebral cortex , cerebellum , brain stem, spinal cord! Concerned with life functions ! (respiration, body temperature) ! Concerned with ipsilateral motor ! control (receives sensory inputs and ! sends motor outputs)!
